Specification of Letters Patent. i

Application led September 16, 1914. l Serial No. 862,078.

l 17 'o all whom it may concern Be it knownvthat I, POLLARD F. I-IoLRoYD, a citizen of the United States, residing at Bridgeport, in the county of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Radiator- Coolers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius tov make and use the saine.

This invention relates to automobile appliances and more particularly to a device adapted for application to the radiator of an automobile to promote rapid cooling of the engine.

An object of the invention resides in the provision of a novel and eiiicient appliance l of the above character which is designed to relieve the radiator of the presence of heated air and steam and thereby prevent same becoming unduly heated.

A further obfect of the invention is to provide a device of the kind specified whereby the heated air and steam rising in the radiator will be drawn off through the radiator cap and cold air admitted thereto through the usual overflow pipe, thereby rendering the radiator comparatively cool and minimizing the possibility of boiling the water as frequently7 occurs during eX- cessive employment of the low and intermediate gearing of the machine.

Still another object of the invention is to provide a deviceof the above nature, that while being possessed of extreme utility may be constructed in such manner as to appear as an appropriate ornament to any automobile onl which it is placed.

With the above and other objects of similar nature in view, the invention consists in the construction, combination and arrangement of parts, set forth in and falling within the scope of the appended claims.

In the drawing: Figure 1 is a fragmentary elevation of an automobile radiator with the invention applied thereto, Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. ljand Fig. 3 is a vertical sectional view taken at rightangles to Fig. 2.

Referring non1 more particularly to the drawing, the numeral 10 designates an automobile radiator, 11 the illing'opening thereof and 12 the cap whereby said opening y1s closed, all constructed in the ordinary manner.

Formed in the face of the cap" 12 is an opening 13 in which is engaged the stem 14 of a plug 15, said plug being provided with a longitudinal bore A16, which communlcates with the filling opening of the radiator. To retain the plug in position on the cap there is engaged 011 the threaded end thereof a nut 16.

Extending vertically from the upper portion of the plug 15 is an armor bracket 17 which carries at .its free end a laterally directed stub shaft 1S. There is mounted for rotation on the shaft 18 a fan 19, the blades 20 of which are pitched in such Inanneras to create a side suction when the machine is in motion. Surrounding this Patented Apr. 11, 1916'.

fan and likewise cast integral with the plug 15 is an annular easing 21, the same representing the rim and tire of an automobile wheel with the lower half thereof provided with a semi-circular passage 22 leading to the bore 16 of the plug, said casing lbeing provided at diametrically opposite points on its ,inner periphery with outlet openings 23, which communicate through the medium of the passage 22 and bore 16 with the interior of the radiator. It may further be added that to insure proper operation of the device there is arranged inthe bore 16 of the plug and dividing the passage 22, a partition 25, said partition directing the heated air toward either or both of the outlet openings 23. In this way should there be any tendency of the fan; to force the cool air into the radiator through one ofthe openings 23, passage of heated air and steam outwardly of the other opening would be in no way in- It is thus apparent that,

terefered with'. when the machine is propelled over the ground, the fan 19 will be caused to rotate, thereby creating suflicient suction to draw the heated air and steam, rising from the radiator, out through the discharge openings 23 such heated air and steam being replaced by a supply of cooler air which is drawn up through the overflow pipe 24 commonly employed in the present type of radiator. It will therefore be observed that a continuous current of cool air will at all timesl be circulated through the radiator above'the level of the water thereof and the latter thus materially assisted in performing the function for which it is intended.l It will further be observed that because of its peculiar construction, this article, when applied, has the appearance of an automobile wheel in miniature, and rather than detract from the appearance of the machine, it will on the other hand materially add thereto by reason of its appropriate orna-f mentality.

Gopies of this patent may be obtained for ve cents each, by `addressing* the Commissioner of Eoteatsy radiator including a filling opening and an overflow-pipe adjacent thereto, of a casing arranged exteriorly of the radiator and having' conin'iunication therewith through `the filling opening, and a fan rotatablyT supported inthe casing for \\'ithdrawing heated ail' and steanl rising Within theradiator and replacing the. Same b v cooler air drawn inwardly through the overlo\\'pipe.

In testimony whereof. I atlix my signature, .in the presence of two witnesses.
